Soil Moisture Sensor

10HS Soil Moisture 300 dpiThe 10HS smart sensor from Onset measures a large, 1-liter volume of soil to help average out any soil variability. To use, simply plug the sensor into an Onset HOBO U30 or H21 Weather Station and begin monitoring without additional wiring or programming. Readings from the 10-cm probe are provided in volumetric water content. The sensor uses a high-frequency (70 MHz) circuit that provides good accuracy even in high-salinity and sandy soils. Compatibility with a range of Onset HOBO Weather Station products gives users a choice as to how they access their soil measurement data. This includes direct data offload in the field using a HOBO data shuttle or laptop, or remotely accessing the data with the Internet. Price: $139. For more information, visit

Reduce Spraying Costs

Are you frustrated by applicator booms that continue spraying even after you’ve shut them off? The Flow Back valves from TeeJet Technologies provide rapid shutoff of spray tips when the boom sections are turned off.

According to the company, sprayers with standard valves trap pressure in the boom when they are switched off. As a result, the boom continues spraying for several seconds. The technology behind Flow Back valves includes an extra passage that allows spray solution to return to the tank. This allows boom pressure to be dissipated immediately and is the key to fast shutoff at the boom. The boom remains full of liquid, and spraying resumes immediately when the valves are switched back on. The rapid shutoff eliminates product waste and improves sprayer accuracy by reducing skips, overlaps and resprays.

Flow Back valves are compatible with all levels of sprayer control systems and require no special wiring or plumbing. They also work with automatic boom section control systems. The compact, electrically actuated Flow Back valves are available in three product platforms: 430 FB, 450 FB and 460 FB. Each one is rated for different pressures and flows. Learn more at

Advanced Seed Monitoring

AdvancedSeedMonitoringCheck out the new Advanced Seed Monitoring through the SeedCommand system available from Ag Leader Technology. Advanced Seed Monitoring is available on the Integra display and provides planter performance monitoring of seed meter singulation, skips/doubles and spacing quality, along with population and spacing information for all rows when planting corn. The Integra display features a full-screen planter performance view that includes display items and bar graphs for population, singulation, skips/doubles and spacing quality. All of these features are available while the display is performing guidance, mapping and auto-steer functions. In addition, Advanced Seed Monitoring determines and displays the rows operating at the highest and lowest levels for singulation and population. Visit
